Robert Pattinson's Original Career Choice? Rapping!

Twi-hards go crazy for Robert Pattinson – and it's attention he enjoys – but what if the Brit never became an actor in the first place?

"I used to want to be a rapper when I was, like, 14," the actor says during an appearance on The Oprah Winfrey Show alongside costars Kristen Stewart and Taylor Lautner, which is set to air Thursday.

Rap music wasn't the only American entertainment Pattinson, who turns 24 on Thursday, enjoyed. "I grew up watching American movies and stuff," he tells Oprah.

So, what's it like to star in one of the most popular American movie franchises in recent years?

"It's a great position to be in because you can walk into a room and everybody's screaming," he says of the rapturous fan response, which will only grow stronger as their latest chapter, Eclipse, hits theaters June 30. But Pattinson thinks a lot of the enthusiasm is less about him and more about his character, Edward Cullen.

"It's not really about you," he says. "So, it never really goes to your head and you can kind of participate in it. It's about the fans themselves. A lot of people, they just like doing Twilight-related things."
